Skycalc is an interactive tool which conveniently handles the time-and-the-sky calculations commonly encountered in optical astronomy. It has many features useful for planning observations and at the telescope.
Skycalendar prints a table of sunrise, sunset, moonrise, moonset, and so on, organized on a nightly (double-dated) basis for any site.
This version (posted 2001 February) incorporates some minor upgrades, bug fixes, and enhancements over V4. Most notably, for skycalc:
- colon-separated times and coordinates are now permitted; - the program can be set to read the system clock every time output is called for; - certain small pieces of copyright-protected code have been excised and replaced with original or public-domain versions; - one can now save non-menu site paramters in a file.
And for skycalendar:
- more TeX output options are supported (e.g., one month per page in landscape mode).
The two subdirectories are as follows:
src - contains the source codes for skycalc and skycalendar.
doc - contains a manual in four forms - plain TeX, dvi, postscript, and PDF. Sorry, no HTML manual yet.
